Not really for most small airports. The plane is in the $ 200 per hour range, so a 1 hour out and 1 hour back flight is $ 400 in rental and fuel. The landing fee is more like $10-20 and often free if you buy fuel there.

Only big airports with mandatory ground handling are expensive to land at.

Typical small US airports still don't charge landing fees to light aircraft, but things are changing. Now that ADS-B[1] is deployed widely, airports are looking at automated landing fee charges as another way to soak pilots, just because they now can. A number of companies are sprouting up to meet this demand and offer airports their turnkey systems to monitor and charge everyone who lands, sharing the profit with the airport.

That sounds crappy. Hobby flying is already stupid expensive.

I always envy the US GA scene. So many airports, little or no landing fees, no prior notice required. In the UK it’s almost designed to prevent GA.

And indeed, the burger itself.

Mostly fuel
